Best way to preload route data before accessing the route.
Before rendering the page for a given route, I want to first get the necessary data synchronously. Ideally I'd like to get the data in the page component, but I'm not opposed to doing it in the router file. I've read and tried various approaches, but part of the challenge comes from the fact that there are multiple ways to build components, and the use of certain features varies. In my case, I use CompositionAPI and syntax to build single file components. The VueRouter documentation link talks about "get before navigation" where I have access to beforeRouteEnte

Use Vue, Pinia and Firebase Authentication to get the current user information before the route guard
Recently I started using Pinia as global storage in my Vue3 project. I'm using Firebase for user authentication and trying to load the current user before Vue is initialized. Ideally, everything related to authentication should be in a separate file, using PiniaStore.

On first load, the user object in storage is briefly empty. This is bound to the user
